DT301T Rugged Real Time Kinematic (RTK) Satellite Navigation Tablet

April 11, 2018

DT Research's DT301T Rugged RTK Tablet is a lightweight military-grade tablet purpose-built for GIS mapping applications with Real Time Kinematic (RTK) satellite navigation used to enhance the precision of position data derived from satellite-based positioning systems. This unique tablet enables 3D Point Cloud creation with centimeter-level accuracy – meeting the high standards required for scientific-grade evidence in court.

The DT301T Rugged RTK tablet is military-grade with an IP65 rating, yet lightweight - offering the versatility to be used in the field, office and vehicles. A dual frequency GNSS module is built into the tablet, which uses real-time reference points within 1 – 2-centimeter accuracy to position 3D point clouds created from aerial photogrammetry, using GPS, GLONASS and GALILEO receivers. Users can measure with the RTK GNSS positioning directly using a foldable antenna or connect to an external antenna for more robust receiving and survey grade precision.

The DT301T Rugged RTK tablet is compatible with existing GIS software for mapping applications and brings together the advanced workflow for GIS data capture, accurate positioning and data transmitting. The tablet can be used in a variety of scenarios, including:

Forensic Mapping – Public safety teams, investigators and crash reconstructionists can use the DT301T Rugged RTK Tablet to accurately collect measurements that are scientifically defensible by using the real-time centimeter reference points to position 3D point clouds created from aerial photogrammetry or take stand-alone measurements. 

Land Surveying – Surveyors can use the DT301T Rugged RTK tablet to measure the altitudes, angles and distances on the land surface so that they can be accurately plotted on a map to determine property boundaries, construction layout and mapmaking.

e-Construction – Construction workers can manage the collection, review, approval and distribution of highway construction contract documents in a paperless environment using the DT301 Rugged RTK tablet.

Building Information Modeling (BIM) – Architecture, engineering, and construction (AEC) professionals can use the tablet to create 3D models to efficiently plan, design, construct, and manage buildings and infrastructure.

The DT301T Rugged RTK Tablet has been purpose-built for precision mapping in a variety of environments and includes the following features and capabilities:

  • Dual Frequency GNSS Module – GNSS L1 & L2 RTK that receives GPS, GLONASS and GALILEO signals up to 372 channels with RMS 10 mm + 1ppm accuracy.
  • High Performance CPU and Windows OS – Intel® 6th Generation Core i5 or i7 processor with MicrosoftWindows® 7 Professional or Windows® 10 IoT Enterprise. Units come with either 8 GB or 16 GB of RAM. 
  • Brilliant Sunlight-readable Display – A 10.1 inch LED-backlight, sunlight-readable screen with capacitive touch and 1920 x 1200 resolution.
  • Superior Wireless Connectivity – Long Range Class 1 Bluetooth powers connectivity up to 1,000 feet and 4G mobile broadband for LTE, HESPA+, GMS/GPRS/EDGE, EV-DO, Rev A and 1xRTT.
  • Superior Storage – For ideal field data collecting, the tablet can store up to 1 Terabyte of data.
  • Military Standards – For use in harsh environments, the tablet is fully ruggedized to meet the highest durability standards with an IP65 rating, MIL-STD-810G for vibration and shock resistance and MIL-STD-461F for EMI and EMC tolerance.
  • High Capacity Hot-Swappable Battery Pack – Delivers 60 or 90 watts for up to 15 hours of continuous mobile communications.
  • Accessories - The DT301T Rugged RTK Tablet is complemented by a variety of accessories, including: external antennas, pole mount cradles, detachable keyboards, battery charging kits, and digital pens.
